问答题Not so long ago, people talked about global warming in apocalyptic terms—imagining the Statue of Liberty up to its chin in water or an onslaught of tropical diseases in Oslo. Recently, however, advances in our understanding of climate have moved global warming from a subject for a summer disaster movie to a serious but manageable scientific and policy issue. The greenhouse effect is nothing new; it has been operating ever since the earth formed. Without it, the surface of the globe would be a frigid –20 ℃ (–4 °F), the oceans would have frozen, and no life would have developed.

问答题nder the law of competition, the employer of thousands is forced into the strictest economies, among which the rates paid to labor figure prominently. The price which society pays for t he law, like the price it pays for cheap comforts and luxuries, is great, but the advantages of this law are also greater than its cost—for it is to this law that we owe our wonderful material development, which brings improved conditions in its train. But, whether the law be benign or not, we cannot evade it；or the effect of any new substitutes for it proposed We can not be sure: and while the law may be sometimes hard for the individual, it is best for the race, because it insures the survival of the fittest in every department. We accept and welcome, therefore. as conditions to which we must accommodate ourselves, great inequality of environment；the concentration of business, industrial and commercial, in the hands of a few；and the law of competition between these, as being not only beneficial, but essential to the future progress of the race.
